LISTING-PLOW. 5;;

Specification of Letters Patent.

' Patented Sept. 24;, 1907.

Application filed June 25,1907. Serial No. 380,714.

To all 'whom it may concern:

Be it known that I, GoTTEmn PERssON, a citizen of the United States, residing at Elgin, in the county of Bastrop and State of Texas, have invented a new and useful Listing-Plow, of which the following is a specification.

This invention has relation to listing plows and it consists in the novel construction and arrangement of its parts as hereinafter shown and described.

The object of the invention is to provide a plow oi the character indicated which is provided with a pivoted foot having at its heel a ground wheel. The said foot is pivoted to a standard extension of the plow beam and lever mechanism is provided for swinging said foot vertically. Listing disks are joln'naled to arms which in turn are pivoted to the plow beams. The said disks are located behind the heel of the foot and lever mechanism is provided for swinging the arms vertically and for moving the disks correspondingly. By reason of the adjustments of the various parts the plow may be readily adjusted to operate in foul or clean soil, sandy or heavy loam.

In the accompanying drawingz-Figure 1 is a side elevation of the plow, and Fig. 2 is a rear elevation with parts in section.

The plow consists of the beam 1, the rear portion of which is continued into the standard 2. The bar 3 is pivoted to the lower end of the standard 2 and the forward end of said bar is pointed and cuneiform as at 4. The side sweeps 5 are attached to the bar immediately behind the portion 4 thereof. The link 6 is pivotally attached to the rear end of the bar 3 and the upper end of said link is pivotally attached to the lever 7 which is provided with a pawl'8 adapted to engage the teeth of the ratchet segment 9. Said segment is located upon the rear portion of the beam 1. The ground wheel 10 is journaled to the bar 3 and is located behind the standard 2 and follows in alinement with the portion 4 of the said bar.

From the above description it is obvious that by swinging the lever 7 that through the connecting link 6 the bar 3 will be swung upon its pivotal connection with the standard 2 so that the said bar and the pointed end 4 thereof will be presented to the ground at a desired angle in order to meet soil conditions.

The arms 11 are pivoted at their forward ends to the sides of the beam 1 and are brought together under the beam and secured together by means of the bolt 12. The said arms then spread apart and pass along the opposite sides of the standard 2. The disks 13 are journaled upon the arms 11 in the vicinity of the standard 2. The extreme rear portion of the arms 11 extend behind the pivotal points of the disks 13 and are provided with the journaled wheels 14 upon the peripheries of which the rear sides of the disks 13 bear. Thus the arms 11 brace the disks 13 at their rear portions which pdrtions are subjected to the greatest strain during the operation of listing the earth. The cross piece 15 is located behind the standard 2 and is attached at its ends to the arms 11. The link 16 is pivoted at its lower end to the cross-piece l5 and at its upper end is pivoted to the lever 17. The said lever is fulcrumed to the beam 1 and is provided with a pawl 18 which is adapted to engage the teeth 19 of the gear segment 20. The segment 20 is also attached to the beam 1. The handles 21 are attached at their lower ends to the lower portion of the standard 2 and the braces 22 connect the intermediate portions of the handles 21 with the beam 1.

By swinging the lever 17 it is obvious that the arms 11 will be swung through the cross piece 15 and link 16. Thus the disks 13 are raised or lowered in order to meet requirements demanded as a condition of the soil.

Having described my invention what I claim as new and desire to secure by Letters-Patent is:-

1. A plow comprising a beam having a standard, a plow foot pivoted to the standard, lever mechanism for swinging the foot vertically, arms pivoted to the beam, disks journaled for rotation upon the arms and a lever mechanism for swinging the arms vertically.

2. A plow comprising a beam having a standard, a plow foot pivoted to the standard and having a ground wheel journaled at its heel, a lever mechanism for swinging the foot vertically, arms pivoted to the beam, disks journaled for rotation upon the arm and a lever mechanism for swinging the said arms vertically.

3. A plow comprising a beam having a standard, a bar pivoted to the standard and having a cuneiform forward end, side sweeps attached to the forward portion of said bar, a ground wheel journaled to the rear portion of the bar, a lever mechanism for swinging the bar vertically on its pivot, arms pivoted to the beam, disks journaled for rotation upon the arms and a lever mechanism for swinging the arms "ertically.

4. A plow comprising" a beam having a standard, a plow foot pivoted to the standard, a lever mechanism for swinging said foot vertically, arms pivoted to the beam, disks journaled for rotation upon the arms at points between the ends thereof, the rear portions of the arms extending toward the rear edges of the disks, wheels journaled upon the rear ends of the arms and bearing against the inner sides of the disks and a lever mechanism for swinging the arms-vertically.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.
